Our purpose was to assess the role of preoperative radio-therapy +/− neoadjuvant chemotherapy in nonmetastatic soft tissue sarcoma of extremities for limb-sparing surgery and identify the role of neoadjuvant therapies on local control and survival rate. Forty-seven patients with soft tissue sarcoma of extremities who were treated at Cerrahpasa Medical Faculty within a limb salvage protocol, including preoperative radiotherapy +/− chemotherapy were retrospectively analized. Median age was 45 years (17–72 years). The tumor size was between 5–33 cm. Seventeen patients were in stage I, 11 in stage II, 19 in stage III. The most common histology was synovial sarcoma. Nine patients were treated for locally recurrent tumour. The tumour and surrounding tissues with probable microscopic tumour involvement observed clinically and radiologically, were irradiated. Thirty-two patients, with a high grade tumour and/or tumours larger than 8 cm, also received neoadjuvant chemotherapy. Neoadjuvant chemotherapy regimen was consisted of doxorubicine and ifosphamide with mesna. Preoperative radiotherapy was applied, usually between the second and third cycles of chemotherapy. Definitive surgery was administered 2–6 weeks after radiotherapy or after the third cycle of chemotherapy. Chemotherapy was completed to 6 courses after the surgery. Postoperative external beam radio-therapy boost of 16 Gy was given who had close or positive surgical margins. Median follow-up time was 67 months (12–217 months). All of the patients had limb-sparing surgery. Patients had; 30 marginal excision, 13 wide local excision, 4 radical resection. Nine patients locally recurred. Limb-sparing surgery was performed for 8 patients. 25 patients had distant metastases. Metastasectomy were applied for 10 patients with lung metastasis. The 5-year local control, disease free survival and overall survival rates were 82.3%, 50.1% and 67.2%, respectively. Preoperative radiotherapy +/− chemotherapy seems to increase the chance of extremity-sparing surgery with good local control and the survival rates which were comparable with the literature.
